While computer keyboards are a massive step up from pen and paper in terms of efficiency, there are always some problems with any technology. In this case, it’s that some of the letters and numbers can closely resemble each other, leading to lots of confusion about which is which.
For example, the number zero 0 and the capital letter O can look a whole lot alike depending on the font that your computer or smartphone is using. If you’re trying to enter something like a network password that has both numbers and letters, this can be pretty tricky!
This led to the creation of the slashed zero or dotted zero to make sure people could distinguish between the two. But then some people had trouble telling the slashed zero apart from the letter 8 in bad lighting or in low resolution. So no easy fix there!
But 0 (zero) isn’t the only one that can resemble (the letter) O. In fact, the letter D can also often resemble the letter O, depending on font settings, occasionally leading to a lot more confusion.
Today, we’ve got a tough challenge for all you wannabe spies and coders. Can you count the number of Ds in the block of Os below in less than 10 seconds? On your mark, get set, go!
How did you do? I bet your eyes hurt just a little bit after working so hard to try to figure this one out. To many people, it just looks like a big long block of unending text. But in fact, there are nine Ds scattered throughout the block.
Can you see which lines they are on? Overall, there are 10 lines of Os/Ds in the puzzle. If you’re still having trouble identifying them, here’s a hint: you can find Ds on the first, second, third, fifth, sixth, eighth, ninth, and tenth lines.
But if the fourth and seventh lines have no Ds, that means that one other line must have two. Can you figure out which one it is?
The way to identify the Ds is to look for the straight line forming the “back” of the D. Another way to find them is to tilt your head to the left so that you can see the resemblance they have with a smiley face or sticking-the-tongue-out emojis, along the lines of this 🙂
Once you’ve got the shape on the first line, the next ones should get easier and easier to identify. If you look a little bit closer, you’ll notice that the fifth line, right in the middle of the puzzle, has not one but two Ds! Now you’ve got the total of nine.
If you were able to get these randomly placed Ds, you’re probably in quite a minority. Many people have difficulty identifying these tiny differences in the shape of the letters especially when you see such a massive ocean of Os.
Take it as a compliment; you probably would have made a great coder/decoder in the days of James Bond!
If you enjoyed this puzzle, why not share it with your friends and family, if nothing else than for the pleasure of seeing them go cross-eyed as they struggle to identify the odd letters out!
